Power and Data Connections and
Terminations
IMPORTANT:
See top of Page 1 for restrictions on
the number of outdoor domes connected to P1–P6.
1. Strip the three power and two data leads from
the composite cable and attach them to a
5-position compression connector, following the
P1–P6 Connector table from Figure 4.
2. Plug the compression connector into an
available port (P1–P6) on the PCB.
3. Wire the SensorNet data cable coming from the
host device (and any cables going to an
auxiliary J-Box or other SensorNet device) to a
4-position compression connector, following the
P8 Connector table from Figure 4.
4. Plug the compression connector into port P8 on
the PCB.
5. Set jumpers JW1, JW2, JW3, and JW4 on the
PCB (see Figure 4) to the correct position.
Shorting pins 1–2 terminates the device. Refer
to the SensorNet Network Guide to determine
the necessary terminations for the chosen
network topology.

Data and Power LED Indicators
The LED indicators on the PCB (see Figure 5)
allow visual verification of SensorNet signals and
power to the dome port and host/auxiliary ports.
They illuminate to indicate the following conditions:
•
AC PWR
is yellow when 24Vac from the
transformer to the PCB is present.
•
+5VDC
is green when DC power from the on-
board regulator is present.
•
FALSE CD
is red for 0.5 sec if the device
receives a false pulse (indicating noise on the
SensorNet cable).
•
123
is yellow for 30ms to indicate
communications activity from dome ports 1, 2,
or 3.
•
456
is yellow for 30ms to indicate
communications activity from dome ports 4, 5,
or 6.
•
AUX
is yellow for 30ms to indicate
communications activity from the auxiliary port.
•
HOST
is yellow for 30ms to indicate
communications activity from the host port.
